SC2446AITSTRT Overview


With a 28-TSSOP (0.173, 4.40mm Width) package, the switching controller is suitable for a wide range of applications. It is sufficient to generate 2 outputs with this dc motor controller. An enclosure of Tape & Reel (TR) is used to package the PMIC. The program can handle PWM Signal dc switching's outputs (s). This dc control has a supply voltage and operating voltage of 4.7V~16V. Workable in an dc switcher where -40°C~125°C TJ is the -40°C~125°C TJrm. A switching controller such as this can switch at a value of 500kHz . A generalization of dc dc regulator can be made using Surface Mount. Featured in the dcdc regulator is Enable, Frequency Control, Soft Start which allows efficient switching control. Connected to a DUAL SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. Thare switching converters has a terminal (s) at DUAL . Different dc switching's functions can be applied to 28 terminations. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. The nominal DC switcher's voltage input is 12V. Other relevant dc to dc converter ics can be found by searching "SC2446". Switching converter type is specifically Switching Regulator or Controllers. dc dc voltage regulators should have a minimum input voltage of 4.7V. A maximum voltage of 16V is accepted by the dc to dc regulator as an input voltage. The duty cycle of the voltage regulator dc to dc can be set to 88 % on power-up or power-down to ensure reliability. A maximum value of 0.005A is output for current.
